In this article, the concepts of construction of the next generation networks are considered. The analysis of the main technological features that distinguish infocommunication services from the services of traditional communication networks was done. It is determined that the next generation network should provide the transmission of all types of media traffic and the distributed provision of an unlimited range of infocommunication services with the possibility of their scaling. For some infocommunication services, the order of packet arrival, packet delay and delay variation (jitter) are critical. It is necessary to guarantee the delivery of information such as speech, video and multimedia in real time with the minimum possible delay. For this purpose, the network must be implemented mechanisms to ensure the required quality of service (Quality of Service-QoS). There are two models to ensure guaranteed quality of service: integrated service of different types of traffic (IntServ) and differentiated services of different types of traffic (DiffServ). The expediency of the joint use of these two models has been proved, moreover, on the trunk sections of the network it is better to use the model of differentiated service of heterogeneous traffic, while using the RSVP protocol, the problem of resource reservation is solved for aggregated data flows. The mechanisms of traffic generation at the network domain boundary and processing algorithms of queue service have been determined. The minimum requirement which is presented for a queuing algorithm service that supports QoS functions is the ability to differentiate and define processing requirements for different packets. According to these parameters, the service algorithm must plan the order of transmission of queued packets. The frequency of service of packets of the same traffic stream determines the bandwidth allocated to this stream.
